一般描述

Reactive group: Carboxylic acid.

应用

The organic layer of the CdS/ZnS or CdSe/ZnS quantum dots (QDs) with carboxylic acid as reactive group consist of a monolayer of oleic acid/octadecylamine and a monolayer of amphiphilic polymer. The total thickness of organic layers on these QDs is approximately 4 nm. They find many applications in bioimaging and biosensing.

We report a multilayer solution-processed blue light-emitting diode based on colloidal core/shell CdS/ZnS nanocrystal quantum dots (QDs). At a low-operating voltage of 5.5 V, the device emits spectrally pure blue radiation at 460 nm with a narrow full-width-at-half-maximum bandwidth of...
技术文章
Dr. Delehanty and researcher introduce recent advances in the use of cadmium-free quantum dots for bioimaging. Focus is placed on strategies that have emerged in the last five years for design, synthesis, and surface modifications of non-Cd quantum dots (QDs) for bioimaging and sensing applications.
